About the communities in Portugal....do you think i sould go to one??
Well, it's not for me to tell you what to do or not to do.
You can practice by yourself to some extent in the event of not finding any suitable community but it is very limiting and frustrating at times, especially when things go wrong or when one is in doubt. But otherwise, the reason for joining a group or community should be as what is laid out here
Will they teach me all the knowledge about buddhism and about meditation and also about the path??
In an ideal way, yes. But we don't live in an ideal world. So, you may expect that some places may have challenges like lack of money, experienced teachers, structured courses, human resources and so forth.
Some may only have certain common features like meditation sessions, ritual chanting or social functions but no formal classes or teaching of the Buddha Dharma and various combinations. So, three ways may be looked at this:
a. either you keep searching for a place that can cater for all (in the worst scenario, even outside of Portugal)
b. or be patient enough to explore through with one group and then over time, at least about a year or so, get introduced to and familiarise with senior students, serious practice and qualified teachers:
i. where they can recommend or have annual programmes with other sister centres elsewhere outside of Portugal
ii. or if they are fortunate enough, they have visiting teachers coming in like once a month/year who will stay for say a week or month long to impart teachings and practices.
c. last resort and backup: search for a good and solid online Buddhist community via group discussions and forums
d. Like in any system of belief, there are cults or controversial groups in Buddhism which are not in the mainstream or even within the mainstream, there are abuses going on. After all, human organisations are not free from human failures as none of us are saints yet. So, it helps to keep one's eyes on the Teaching & Discipline per se rather than to judge merely by the conduct of mere humans who have faults just like my own self. I will not name anyone or any group here but will leave that research for your own homework and decision. But it is sufficient to mention here that this is one aspect to keep in mind about in one's journey as a practitioner versus having a naive and unrealistic idealism & assumption about things and people only to be unnecessarily disappointed and discouraged later.
Lastly, when one goes into any center, an open mind, helpful heart and having less expectations will prove helpful in the long term.
That way, you save yourself in some way from the common human disappointment & discouragement and helps with effective interaction with others.
I also have one more question....i was reading the texts that you gave me and i wonder if i by meditation, for example, could achieve peace and wisdom and full truth without knowing the buddhas live, the four noble truhts, etc...
Correct me if I am wrong and if I have interpreted your question correctly, there are two ways to look at this:
a. one may engage with the practice of meditation in a mundane way for mundane results:
i. for various reasons only known to the person, for example:
curiosity, non-commitment, with a certain aim in mind like simple benefits of a peaceful mind and life or a more complicated one like wanting psychic powers.
ii. nothing connected with what the Buddha taught on the practice of meditation as laid out in the Path and Stages
iii. Yes, what you mention on 'peace, wisdom and full truth' have different meanings to different people. Not everyone wants the Buddha's version of those terms but may not mind trying out the methods he taught.
b. one engages in meditation as how a true practitioner should: as part of the Path & Fruit as how it is mapped out by the Buddha, both with mundane and supramundane in mind, with visible results in the here and now plus beyond.
